Granted: 2000-06-23
Abstract: The injection grout (type CPA-CEM I), after initial setting, has a shear threshold of 4 Pa or more, and initial viscosity of 0.3 Pa.s, all testing being at 20 [deg] C, in accordance with Fann methodology. No traces of exudation are visible, following a 24 hour, inclined-tube test (see figure). Independent claims are included. These cover: a kit based on the materials described, used to make up the grout; a civil engineering structure including prestressing cables in such grouting; and the method of quality verification by Fann testing and measurements as prescribed. Uses are also claimed (see appropriate heading). Preferred features: A Portland cement base is used, the cement having a specific area of 3000-3200 cm2>/gm. The sulfate content is 1.5-2.5 wt %. E/C ratio is 0.32-0.38. The (super) plasticizer amounts to 0.5-1.5 wt %, based on dry weight, in relation to the total weight of cement present. Further percentages of plasticizer and viscosity modification agents are quantified in accordance with type. Quantified formulations based on the foregoing principles are also provided.

Title: Method for particle size distribution control in a bayer circuit decomposition chain, comprising an agglomeration phase
Inventor: CRISTOL BENOFT
IPC: C01F7/144
Filed: 1999-08-12
Abstract: In a BAYER circuit, a process for controlling precipitation in which particle size quality of alumina hydrate produced in the circuit and circulating in feed tanks is monitored utilizing a calibration step and a control step. In the calibration step, cumulative percentage of alumina hydrate particles circulating in the feed tanks in the circuit that are finer than X2 mum, defined as CPFT X2, is measured vs. time and cumulative percentage of alumina hydrate particles circulating in the feed tanks in the circuit that are finer that X1 mum, defined as CPFT X1 vs. time, is measured, where X1 and X2 are predetermined particles sizes and X1 is smaller than X2. A relationship R between CPFT X1 and later changes in CPFT X2, is determined and upper and lower trigger thresholds of CPFT X1 which correspond to maximum permissible variation in CPFT X2 are defined. In the control step, CPFT X1 and CPFT X2 are regularly measured, and R and the correlation between CPFT X2 and the particle size of hydrate produced are updated. Corrective action is taken at the beginning of precipitation when the measured value of CPFT X1 reaches one of the trigger thresholds.

Title: Gas stove for preventing cookware from getting rusty
Inventor: XIANFENG WU
IPC: F24C15/10
Filed: 2020-09-16
Granted: 2020-11-23
Abstract: This application provides a gas stove for preventing cookware from getting rusty, to enable residual moisture in cookware to evaporate quickly every time after cooking ends and after each washing. On the basis of a conventional gas stove, the gas stove is added with an evaporation 5 device and a control system. In actual applications, a temperature sensor in the control system may detect a temperature within an area of a combustion device, and a time point for starting the evaporation device is determined by the controller based on the detected temperature, to control a heat source mechanism in the evaporation device to generate heat output. Heat is transmitted to the cookware by a heating tube, so that a temperature of the cookware rises, thus accelerating 10 evaporation of the residual moisture in the cookware, to prevent the cookware from getting rusty. In actual applications, the gas stove provided in this application may provide a heat source for the cookware by using the evaporation device. The heat source is independent from the combustion device of the gas stove. Therefore, the residual moisture in the cookware may evaporate quickly through an independent heating manner, without igniting the combustion 15 device again, thus avoiding a risk of gas leakage. 16
